Portrait Blur: how to use it
- Drop in a photo of a person, pet or object.
- Choose the Blur strength, from light to extra strong.
- Choose the Background look: keep the colours, slightly darker, or black and white. Then blur.
Tips
- Real lens blur increases with distance. A medium strength usually looks more believable than extra strong.
- If fine edges such as hair look cut out, try the Best edges model.
- For blur across the whole image, or motion and radial blur, use the Blur Tool.
Portrait Blur: what it does and when to use it
Phone cameras fake a shallow depth of field in portrait mode by separating the subject from the background and blurring the background. Portrait Blur does the same to any photo after the fact: a segmentation model finds the person, pet or object, the rest of the picture is blurred in your browser, and the sharp subject is placed back on top.
Pick a strength to suit the shot. Light keeps the setting recognisable, which suits travel photos; Strong and Extra strong isolate the subject like a fast portrait lens. Slightly darker or Black and white backgrounds push attention further towards the subject. The Fast model is tuned for people; Best edges handles other subjects and fine outlines.
The blur is even across the whole background, whereas a real lens blurs more the farther away something is, so scenes with a floor or ground running into the distance can look flatter than a true portrait shot. Edges with loose hair are the most likely to show a halo; check them at full size. To blur only part of an image by hand, use the Image Blur tool.
Portrait Blur: frequently asked questions
Is the Portrait Blur free, and do I need to sign up?
Yes, the Portrait Blur is 100% free with no sign-up, no login and no account. The Portrait Blur runs its AI model on your own device, so it has no credits, no daily limit and no upload, and saves at full resolution with no watermark. See why it is free.
How do I blur the background of a photo?
Upload the photo and press Blur background. An AI model running in your browser finds the person or object in front and the background is blurred around it, so you get a phone portrait-mode look from any photo, including ones taken without it.
Can I change how strong the blur is?
Yes: light, medium, strong or extra strong. You can also make the background slightly darker or black and white so the subject stands out even more.
Why is the edge around hair sometimes soft?
Fine hair and see-through things like glasses are the hardest part of any cut-out, so a little of the background can stay sharp next to them. A plain background behind the subject gives the cleanest edge.
Is there a free alternative to portrait mode?
Yes. This tool gives any photo a portrait-mode background blur on your own device, even if it was taken without portrait mode. For a background you choose yourself, use the Background Replacer.
